Overview
Description
Auto set
WattStopper’s DT-200 Series Dual Technology
Ceiling Sensors combine PIR and ultrasonic
technologies into one unit to achieve precise
coverage in detecting occupancy.
The DT-200 requires no adjustment at installation.
Auto set continuously monitors the controlled
space to identify usage patterns. Based on these
patterns, units automatically adjust time delay
and sensitivity settings for optimal performance
and energy efficiency. Sensors assign short delays
(as low as five minutes) for times when the space
is usually vacant, and longer delays (up to 30
minutes) for busier times.
Operation
Low voltage DT-200 Series Sensors utilize a
WattStopper power pack to turn lights on when
both PIR and ultrasonic technologies detect
occupancy. They can also work with a low voltage
switch for manual-on operation. PIR technology
senses motion via a change in infrared energy
within the controlled area, whereas ultrasonic
uses 40 kHz high frequency ultrasound. Once on,
detection by either technology holds lights on.
When no occupancy is detected for the length
of the time delay, lights turns off. DT-200 Series
Sensors can also be set to trigger lights on when
either technology or both detect occupancy, or to
require both technologies to hold lighting on.
Features
• Advanced control logic based on RISC
microcontroller provides:
- Detection Signature Processing to eliminate
false triggers and provides immunity to RFI
and EMI
- Walk-through Mode turns lights off three
minutes after the area is initially occupied –
ideal for brief visits, such as mail delivery
- Available with built-in light level sensor featuring simple, one-step setup

Application
DT-200 Series Sensors have the flexibility to work
in a variety of applications. Mounted at ten feet, the
sensors can cover up to 2000 square feet of walking
motion and 1000 square feet of desktop motion.
The sensors are designed to control lighting in
difficult applications where one technology alone
could encounter false triggers. The DT-200 works
well in classrooms, warehouses, large offices, open
office spaces and computer rooms. • Sensors work with low-voltage momentary
switches to provide manual control
• LEDs indicate occupancy detection
• Eight occupancy logic options provide the ability
to customize control to meet application needs
• Available with isolated relay for integration with
BAS or HVAC
• Swivel mounting bracket for convenient corner
mounting to wall or ceiling
• Qualifies for ARRA-funded public works projects
